Implementation Reference
- The main handler function for 'analyze_requirements' tool. Parses input requirements, categorizes them by type, priority (MoSCoW), complexity, risk, estimates effort, identifies stakeholders, computes breakdowns, and returns a comprehensive Markdown-formatted analysis report.
